Specification of Letters Patent.

Patented nee. a, rear.

Application filed October 25, 1916. Serial No. 127,553.

' To all whom it may concern:

'is a specification, reference being had therein to the accompanying drawings. 7

llt is one of the objects of the invention to obtain a construction of gun in which a loud report may be produced without the discharge of any projectile; further to provide mechanism for repeated operation; and still further to obtain a construction which closely simulates a fire-arm of the pump gun type. With these and other objects in view the invention comprises various features of construction as hereinafter set forth.

In the drawings:

Figure 1 is a side elevation of the gun;

Fig. 2 is a longitudinal section thereof;

Fi 3 is a similar section showing the members in a different position of a justment;

Fig. 4 is a section on line 21-00 Fig. 2.

A is the stock and B the barrel of the gun, the latter being preferably formed from a sheet-metal blank, with a frame portion C integral therewith and forming the attachment to the stock. D is a handle arranged below the barrel and slidable in relation thereto, having the appearance of the handle used in a pump gun.

To produce the report a cork or other tight-fitting plug is inserted in an air cylinder and upon compression of the air therein is ejected. Both cork and cylinder are concealed within the barrel B, and by reciprocating the handle D the cork is first engaged with the cylinder and the air is then compressed. Preferably the cylinder E is slidable within the barrel B and is attached to the handle by a strap 1F preferably integral with the cylinder and projecting downward through a slot in the barrel. The strap is provided with the parallel flanges G and G, which engage a longitudinal slit H in the handle and have prongs I passing through bores in the handle and then clenched at the bottom thereof. The clenches may be Within the barrel E is a piston K having a shank L anchored at its rear end to the barrel B. M is a buffer spring sleeved upon the shank within the barrel, its rear end abutting against the stock and its forward end against the cylinder when retracted, which latter is provided with inwardly-extending mtegral ears N forming a bearing for the spr ng. O is the cork or stopper, which is of a size to loosely fit the barrel B and to tightly engage the end of the cylinder E. P 1s an abutment in the forward portion ofthe barrel, which arrests forward movement of the cork but which is centrally apertured for the escape of air. In order that the cork may have a clearance within the barrel B for the escape of air therearound and at the same time tightly fit the cylinder, the latter is formed with a flaring mouth Q, while the cork is formed with a rounded inner end B for engaging said flaring mouth. There is also suiiicient taper'in the sides of the cork to compress the same when inserted and to produce the desired frictional resistance to its expulsion from the cylinder.

With the construction as thus far described in operation, the handle D is moved outward and the cylinderE is forced against the cork 0 while the latter is bearing against the abutment P. This will cause the cork to tightly engage the cylinder, so that when the latter is drawn rearward by a movement of the handle I the cork will be carried therewith. When the handle D is drawn quickly rearward the piston K will compress the air in the cylinder E until sufficient pressure is attained to expel the cork, whereupon a sharp report is produced. The cork is driven forward but the abutment P limits its movement, while the return movement of the handle and cylinder will cause a reengagement of the cork with the cylinder. Thus the gun may be operated successively as frequently as desired.

In order to increase the semblance to a real gun a false trigger is provided, which, however, performs no mechanical function. A simple and inexpensive construction of trigger and guard may be formed by providing the same with shanks which are inserted in bores in the stock A. Thus, as shown, the guard S is a U-shaped strip of metal, the prongs of which are inserted inbores in the stock while the trigger T is provided with a shank T inserted in a bore between the prongs of the guard.

hat I claim as my invention is:

'1. In a gun, the combination with a barrel, of a cylinder, piston and stopper com pletely' concealed and permanently retained within said barrel, and means operable from outside the barrel for alternately engaging said stopper with said cylinder and compressing the air to eject the-stopper.

2. In a gun, the combination with a bar- .rel, of an air-compression cylinder and a stopper therefor completely concealed and permanently retained within said barrel,

and a handle slidable longitudinally of the barrel for actuating said air-compression cylinder, to engage the same with said stepper and to eject the stopper by compressed an.

3. In a gun, the combination with a barrel, of a cylinder within said barrel slidable longitudinally thereof, a piston engaging said cylinder, a stopper for said cylinder,

an abutment for limiting movement of said stopper, and a handle outside of said barrel movable longitudinally thereof and connected with said cylinder, for the purpose described.

4. In a gun, the combination with a barrel, of a cylinder within said barrel of lesser diameter and provided with a flaring mouth,

v rel, a piston for said cylinder, a shank for said piston extending rearward from said cylinder and anchored to said barrel, a butter spring sleeved upon said shank and adapted to abut against said cylinder, a stopper for engaging said cylinder, an abntment for said. stopper, holding the same in position for engagement with said cylinder when pressed forward, and a handle for retracting said cylinder to compress the air and eject said stopper.

6. In a gun, the combination with a barrel, of a member within said barrel movable longitudinally thereofia shank on said member projecting through a slot in said barrel and comprising a fiat plate and a projecting prong, and a handle for engaging said shank having a grooved periphery and a longitudinal slot, the fiat plate portion of said shank engaging said slot and :1 prong projecting through the body of said handle and clenched in said groove.

7. In a gun, the combination with a barrel, of an air compression cylinder :lorined from a sheet-metal blank, having a shank portion extending through a slot in the barrel and provided with a projecting prong, and a handle for engaging said shank slotted to receive the same and bored to receive said prong, the latter being clenched to cure the handle to said shank.

8. In a gun, the combination with a barrel, of a cylinder slidable within said barrel formed of a sheet-metal blank having a portion seamed to form an air tight tube and a portion having parallel shanks projecting through a slot in the barrel and terminating in prongs, and a handle slotted to receive said parallel projections and bored for the passage of said prongs, said prongs being clenched to hold said handle in position.

In testimony whereof I atlix my sign atnre.
